– The Purple Lot, a Lafarge parking lot project at Calgary International
Airport (YYC) which incorporated the use of an amended asphalt mix containing
reclaimed asphalt pavement and Asphalt Shingle Modifier, was recently
recognized by the Canadian Construction Association for its sustainable
features. The project met specifications, reduced waste and permitted mixing to
occur at lower temperatures, reducing emissions at the asphalt plant.

In addition, Lafarge used recycled
concrete in the parking lot sub-base in lieu of virgin material. The recycled
concrete was processed to have the same physical properties as the gravel,
resulting in more than 40,000 tonnes of concrete being diverted from landfills.
An additional benefit occurred in reduced haul distance resulting in a
reduction of over 1,000 tonnes of CO2 emissions.

 

As well, recycled rubber
wheel stops were used in lieu of concrete wheel stops. The project required 650
wheel stops, each of which prevents 2.3 tires from reaching the landfill.

 

“Building sustainably is an
important part of every project at YYC,” said Jody Moseley, Director of
Corporate Communications and Marketing The Calgary Airport Authority. “YYC was
Canada’s first GoGreen certified airport and we continue to focus on new and
innovative ways to develop the airport, while minimizing our environmental
footprint.”

 

For this project,
approximately 1,500 tires were effectively diverted from
landfill. The end results were: more than 42,470 tonnes of material diverted
from landfill and recycled for this project and a reduction of 1392.7 tonnes of
CO2 emissions.
